What GTC Cloud-Fax is
GTC Cloud-Fax is an online service for sending and receiving faxes without a fax machine or fax server. Users can work through a web interface, email, or developer interfaces, and can use those routes in parallel. Its interfaces include REST, SOAP, and SMTP; API features include multiple recipients and scheduled sending. Email sending uses the destination fax number followed by @fax.tc, with delivery status returned by email. Incoming faxes can arrive as PDF or TIFF attachments or be retrieved from a secure reception area. The service also supports cover sheets, address-book recipients, custom sender IDs, centrally managed users and permissions, sending logs, and delivery notifications. GTC says its servers are in Germany and lists GDPR compliance, SSL access, IP-range restrictions, and HIPAA support. A free test account is listed as free, but there is no free plan. Paid options include Paket-Lösung – klein at €9.50 a year, billed monthly with a 12-month minimum, and fax-sending credit at €11.90, paid once. A Germany 01805 reception number is listed at €11.31 a month, plus an 11.31 EUR setup fee.
